In this randomized and controlled trial, 64 adult ambulatory knee arthroscopy patients received either selective spinal anesthesia (SSA) with 4 mg of hyperbaric bupivacaine or general anesthesia (GA) with desflurane. We conducted the study to determine whether SSA with small-dose bupivacaine provides equal fast-tracking possibilities, a shorter stay in the postanesthesia care unit, andearlier discharge home compared with GA with desflurane. Patients with a high risk for postoperative nausea and vomiting received prophylaxis in the GA group. No difference was seen in the fast-tracking possibilities or time in the postanesthesia care unit between the groups. Home readiness was achieved after 114 (31-174) and 129 (28-245) min (NS) in the SSA and GA groups, respectively. In the hospital, the pain scores were significantly (P < 0.001) lower in the SSA group compared with the GA group and the need for postoperative opioids was significantly (P = 0.008) larger after GA. The incidence of postoperative nausea and vomiting was 0% versus 19% in the SSA and GA groups (P = 0.024), respectively. We conclude that for outpatients undergoing knee arthroscopy, SSA with hyperbaric bupivacaine provides equal recovery times with less frequent side effects compared with GA with desflurane.
